Definitely couldve done better but eh ╮(─▽─)╭

(a list of all the clothing he doesn't like would be much, MUCH longer)

1. The Weird Sisters' Concert Outfits

"black robes that had been artfully ripped and torn"

2. Bill Weasley's Whole Look

Bill was — there was no other word for it — cool. He was tall, with long hair that he had tied back in a ponytail. He was wearing an earring with what looked like a fang dangling from it. Bill’s clothes would not have looked out of place at a rock concert, except that Harry recognized his boots to be made, not of leather, but of dragon hide.

A very unusual level of detail from Harry (normally only present when describing outfits he hates.) He's paying attention to the specific material of Bill's shoes, and seems to be drawn to a rock-and-roll sort of look.

3. The Cursed Opal Necklace

a magnificent necklace of opals, Caution: Do Not Touch. Cursed

4. Madame Maxime's Opal Necklace/Ring Set

many magnificent opals gleamed at her throat and on her thick fingers.

I guess Harry likes opals.

5. The Bulgarian Minister's World Cup Look

splendid robes of black velvet trimmed with gold

Harry has been known to be a bit of a magpie when it comes to gold things. Like snitches, and that solid gold cauldron Hagrid wouldn't let him buy, and that solid gold set of gobstones Hagrid also wouldn't let him buy.

6. Yaxley's Ministry of Magic Robes

magnificent, sweeping robes, which were embroidered with much gold thread.

Yaxley's robes are apparently identical to the Bulgarian Minister's robes.

7. Mrs. Weasley's Gold Necklace

spectacular golden necklace

he likes gold things okay

8. Dumbledore's Start-of-Term-Feast Look

magnificent deep green robes embroidered with many stars and moons.

9. Dumbledore's Purple Velvet Dressing Gown

He was wearing a magnificently embroidered purple-and-gold dressing gown over a snowy-white nightshirt

10. Dumbledore's Purple Velvet Suit (Honorable Mention)

“Nice suit, sir,” said Harry, before he could stop himself, but Dumbledore merely chuckled

Honorable mention because of Harry not meaning to say that, and Dumbledore thinking the exchange is funny. Young!Dumbledore is wearing "flamboyant" head-to-toe plum velvet, and Harry is either being sarcastic, or trying very very hard not to say, "That's gay."

11. Slughorn's Funeral Look

magnificent, long, emerald green robes embroidered with silver. 

12. Draco's Dark Green Robes

a handsome set of dark green robes that glittered with pins around the hem and the edges of the sleeves

SO WHAT HAVE WE LEARNED?

~ Harry's style profile is either "rock star" or "elf prince"

~ He likes shiny things, and appreciates jewelry

~ I think his favorite color might be green?

~ Dumbledore can put together an outfit.

~ Harry should get some black-and-gold robes.
